Summer tyres prices

Hello! We have a family car (VW Touran) with 225/45 R17 rims/tires. These have to be restocked this year. Now I have just made myself (for the first price comparison) at Reifen.com and wonder about the bad opaque immense price differences. The Touran is really not a racing car, 190 top, so I do not need high-speed tires. The cheapest offered tire costs 42 Euro (Sunew 225/45 R17 94 W ZR YS618) (Ge W Load 94) Is it worth it for me to buy a “better” mackerel tire (e.g. “recommendation” Vredestein 225/45 R17 94 Y ZR Ultrac Cento XL FSL for 89 Euro ) ? Of course I am interested in saving money but also does not want to do this at the expense of security. Thanks for answers! Greetings,
